SVGm IP54
be used in distorted networks, with no need to add filtering elements to the installation.

4.2.- MEDIUM VOLTAGE

The SVGm is able to compensate for the reactive current in medium voltage with the unit connected
in low voltage. To do this, a current measurement transformer must be used to measure the medium
voltage current.
There is a phase difference in the currents in the primary and secondary transformer coils that de-
pends on the construction of the transformer. To compensate for this difference, the type of transform-
er used and its transformation ratio has to be entered in the settings screen (
This information is available on the transformer's rating plate.

4.3.- SELF-DIAGNOSIS

The device is fitted with a self-diagnosis system. The device checks the integrity of the hardware and
software control elements when starting up. This analysis is carried out according to IEC60730.
This system ensures the device remains in a safe state in the event of failure. The user is alerted to the
failure thanks to an on-screen message and it is also found in the Modbus register.
This type of failure indicates damage or degradation of any of the control and process elements, both
hardware and software. Turning off the device and contacting TAS is recommended whenever this
alarm comes about.

4.4.- THERMAL PROTECTION

The device features several levels of thermal protection:
Ventilation regulation, the fan speed is adjusted as needed at any given time, thus minimising the
noise in the device.
Static temperature limitation, the device reduces its power if the internal temperature exceeds
certain limits. This maximises the availability of the device in any situation.
